Sikorsky Aircraft has handed over the initial offshore-configured S-76D to Bristow Helicopters as part of an order for 26 of the type. Bristow purchased the helicopters in March 2013. The helicopter is the first of the S-76D variant to enter service. FAA issued the type certificate for the S-76D in October 2012, with Sikorsky achieving certification for offshore oil operations a year later. The offshore approval increases the max gross weight to 11,875 lbs with up to 12 passengers.

Bristow will use the S-76Ds primarily for passenger transport to offshore oil and gas rigs. Equipment includes a rotor ice protection system (RIPS), active vibration control, health and usage monitoring system (HUMS) and all-composite rotor blades, with power from Pratt & Whitney Canada PW21S engines and Thales TopDeck avionics.
